Title:
WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2015/162771
Kind Code:
A1
Abstract:
Provided is a wireless communication system which can decode without needing to synchronize the codes. This wireless communication system performs communication using multiple code pairs made up of a code used in encoding and a code used in decoding, and is characterized by being provided with a transmitter which uses one of the codes to encode and transmit communication data, and a receiver which decodes the received communication data using the code paired with the code used by the transmitter to encode said communication data, wherein the code for encoding and the code for decoding are a non-zero value when the paired codes are multiplied by any phase and added across a fixed period, and are approximately 0 when codes of different pairs are multiplied by any phase and added over a fixed period.
